On Monday, one of the researchers linked to the BMJ journal called for European governments to sue Roche.

‘‘I suggest we boycott Roche’s products until they publish missing Tamiflu data,’’ wrote Peter Gotzsche, leader of the Nordic Cochrane Centre in Copenhagen. He said governments should take legal action against Roche to get the money back that was ‘‘needlessly’’ spent on stockpiling Tamiflu.

World Health organization spokesman Gregory Hartl said the agency had enough proof to warrant its use for unusual influenza viruses, like bird flu.

In a statement, Roche said it had complied with all legal requirements on publishing data and provided Gotzsche and his colleagues with 3,200 pages of information.
